What You'll Learn

Change your residential address
If you have changed your residential address, you will need to change your PAN jurisdiction and your AO code. This is necessary so that your new Assessing Officer can process your tax returns in accordance with your new address.
To change your PAN jurisdiction, you will need to write an application to your current AO, stating the reason for the change (i.e. your change of address). You will then need to write an application to your new AO, requesting that they apply to your existing AO for the change. Once your current AO has approved this application, it will be forwarded to the Income Tax Commissioner. After they have approved the application, your AO will be changed.
You can also change your Assessing Officer if you are not satisfied with their behaviour. To do this, write a detailed application and send it to the Income Tax Ombudsman.
To change your AO code, you will need to apply for a new one. You can obtain your new AO code from the nearest Income Tax Department or the official site of the Income Tax Department.

Submit a request to the Income Tax Department
To submit a request to the Income Tax Department to change your PAN AO code, you must follow a few steps. Firstly, it is important to note that you cannot change your AO code unless your residential address changes. This is because the AO code is directly linked to taxation and tax laws that vary according to geographical location.
If you have changed your permanent address, you must change your PAN jurisdiction, which lies with the jurisdictional Assessing Officer (AO) allotted to be assessed when you applied for your PAN card. To do this, you must write an application to your current AO stating the reason for the change, which in this case, is your change of address. Secondly, write an application to the new AO, requesting that they apply to the existing AO for the change. The current AO must then accept this application.
You can find your new Assessing Officer by visiting the official website of the Income Tax Department and clicking on 'Know Your TAN/AO' on the left side of the page. You will then need to select your category and state, and enter your name as per your Aadhar Card, along with a valid mobile number. After reviewing the details, click on 'Continue'. On the next page, you will be able to view the Jurisdiction details of your PAN, including the name of the Assessing Officer, Area Code, AO Type, Range Code, AO Number, Jurisdiction, Building Name, Email ID and Status.
Once you have the details of your new Assessing Officer, you can submit your request to change your PAN AO code. This request must be sent to the Ombudsman and must be signed by you and your representative. Along with the letter, you must also submit relevant supporting documents. Once approved by the Ombudsman, the application is forwarded to the Income Tax Commissioner. After their approval, your present AO will be changed to a new Assessing Officer.

Write an application to your current AO
To change your PAN jurisdiction, you must first write an application to your current AO (Assessing Officer). This letter should include personal details such as your name, age, date of birth, address, and the reason for your request. The only way to change your AO Code is by changing your residential address, so your letter should state this as the reason for your request.
Your AO Code is a 10-digit alphanumeric number that is connected to an assessing officer code in the PAN database. It consists of four elements: Area Code, AO Type, Range Code, and AO Number. The Area Code is a 3-letter code that identifies the geographic location of the individual or company. The AO Type helps the tax department identify the type of PAN Card holder (individual, company, service personnel, or non-resident of India). The Range Type is based on the PAN Card holder's address and helps identify the ward or circle in which they live. The AO Number is a numerical value that is the last part of the AO Code.
In your application, you should also mention the name of the officer you are complaining against and the reason for your complaint. If your current AO is not discharging their duties efficiently or is displaying unprofessional behaviour, you can request a change. Your application should be detailed and sent to the Income Tax Ombudsman.
After writing to your current AO, the next step is to write an application to the new AO, requesting that they apply to the existing AO for the change. This application process will initiate the migration of your PAN to the new Assessing Officer.

This application must include your name, age, date of birth, address, and the name of the officer you are complaining against (if applicable).
